Who is Mr. Sinister?

Origin Nathaniel Essex was born in Victorian England during the 19th Century. He was obsessed with Charles Darwin's Theory of Evolution. Although he was genuinely passionate about his work, he also cared a great deal for his wife Rebecca Essex and their son. Disaster struck when their son died, aged four, of various birth defects. Essex started to intensify his work and theories about evolution to cope with the pain of this loss, ignoring his (again pregnant) wife as a result. Where he was once a passionate and tender man, he became more and more secluded and ignorant to the people around him. Unbeknownst to his wife, Essex even utilized his son's body as a test subject in hopes of figuring out what had caused his death. His research eventually evolved into a theory that humanity was steadily evolving, with various mutations as a possible outcome.
